+ SAN > JetStor NAS 724UXD

2 NAS > JetStor NAS 724UXD

Unified storage for business processing application where high performance SAN is not required

Active – Active architecture Support ALUA, both controllerscan deliver IO at the same time Zero business downtime 99.999% availability

Hybrid storage. Support file-level and block-level I/O, structured and unstructured data Thin provisioning, compression

Active-Active vs Active-StandbyActive – active Active – standby

Fast failoverInter-process communication and heartbeat is achieved using high speed bus on backplane protected by the enclosure.

Slow failoverIPC and heartbeat is carried out using 1Gb Ethernet external cable. It is slow and prone to external errors.

EfficiencySupport all RAID levels in the storage pool. Support global namespace. Both controllers see the same HDD configuration and storage pool.

Waste of resourcesLimited to RAID 1 for HDD mirroring.Because you need to set aside the same HDD capacity in the passive system, it’s a waste of HDD capacity.

Performance scalingBoth controllers can deliver I/O and services at the same time. IOPS can scale 1.5 times.

No performance scalingPassive controller will not deliver I/O. The resource is idle and wasted.

Consistent data after recoveryAfter recovery from controller failure, all disk data remain intact and consistent.

Inconsistent data after recoveryAfter recovery from controller failure, the failed system doesn’t have the latest disk data. Synchronization process is needed and it is time consuming.

ZFS Benefits - Highlights• More than just another FS : file system + volume manager + RAID controller all in one

• Immense scalability : 128bit address space

• End-to-end data integrity– Everything is copy on write, always on disk consistent

– Everything is transactional

– Everything is checksumed, no silent corruption, no bad metadata

– Enhanced data protection : snapshot, replication, pool scrubbing

• Storage efficiency– Thin provisioning, compression

• Simple administration

ZFS Benefits – Data Integrity

ZFS

EXT3EXT4

Most SMB NAS use ext3/ext4 Journal file system, but any unexpected shutdown may crash the Journal file system. This causes some data loss or data inconsistency; the worse case will be the file system crashing and whole data gone …

With JetStor NAS ZFS file system (that once belonged only to very high-end products), there is 0% file system crash possibility and always end-to-end protection of disk data consistency due to its copy-on-write transactional model and self-healing architecture.

ZFS Benefits – Copy on Write

• All or nothing, always on-disk consistent

• Immune to power failure
